There have been concerns that two fractured fingers on his left hand have affected his ball drop and his accuracy.
"It was just a bit of a clean-up," Collingwood football manager Geoff Walsh told the Herald Sun. "He has had a lot of knocks on it over the years and there was a lot of scar tissue in it."
Cloke has played with his middle fingers strapped on a few occasions this year, but has still kicked 34 goals to be right in the hunt for the Coleman Medal.
Cloke is expected to play in Collingwood's next match, away to Port Adelaide on June 29.
